From residential rooftops to commercial campuses and utility-scale grids — one partner for design, supply, integration, and long-term support.
Shanxi Yiwei New Energy Development Co., Ltd. delivers end-to-end PV and energy storage solutions for global clients. We combine high-efficiency modules, storage systems, power equipment, and engineering capability into practical, bankable projects.
Whether you need peak-shaving for a factory, energy independence for a home, or grid flexibility at utility scale, our team supports consultation, system design, product delivery, commissioning, and after-sales service — as a true technical partner for energy transition.

Residential Solar + Storage
Residential Solar + Storage
Smart home energy systems combine rooftop solar, modular batteries, and intelligent control to increase household energy independence while keeping essential loads powered through grid outages.
- Self-generation and self-consumption
- Reliable whole-home or essential-load backup
- Time-of-use optimization and smart management

Commercial & Industrial
C&I Energy Storage
Flexible storage platforms for factories, campuses, commercial buildings, and charging hubs. Intelligent EMS coordinates batteries, solar, loads, and charging infrastructure to lower energy costs and strengthen operating resilience.
- Peak shaving and valley filling
- Demand control and standby power
- Integrated solar, storage, and EV charging

Utility-Scale BESS
Utility-Scale Battery Storage
Modular MW/MWh battery systems support generation, transmission, and distribution networks with fast, controllable capacity and multi-level safety architecture for long-term grid service.
- Peak regulation and frequency response
- Grid-forming operation and resilience
- Renewable energy integration

Solar + Storage
Integrated Solar + Storage
Coordinated PV and storage systems improve solar utilization and create dispatchable clean energy across projects ranging from individual rooftops to industrial parks and utility-scale solar plants.
- Residential and commercial rooftops
- Industrial parks and energy campuses
- Ground-mounted solar power plants

Wind + Storage
Wind + Storage
Battery storage absorbs short-term wind variability and shifts surplus generation into higher-value periods, giving wind farms smoother output and more predictable grid performance.
- Wind power smoothing and ramp control
- Curtailment reduction and energy shifting
- Grid-friendly renewable integration

Wind + Solar + Storage
Wind + Solar + Storage
Hybrid renewable plants combine complementary wind and solar profiles with battery storage. A unified EMS balances generation, storage, grid exchange, and load demand as one coordinated system.
- Complementary multi-energy generation
- Unified EMS scheduling and control
- Stable and dispatchable clean power

Hybrid Microgrid
Wind + Solar + Storage + Diesel/Gas
Hybrid microgrids coordinate renewable generation, batteries, and diesel or gas generators to deliver dependable power where the utility grid is weak, costly, or unavailable.
- Mines, farms, and remote communities
- Island and weak-grid applications
- Automatic source dispatch and fuel savings

Off-Grid & Island
Off-Grid & Island Microgrid
Resilient islanded systems maintain stable voltage and frequency without a strong utility grid. Storage and intelligent controls restore service rapidly and prioritize the loads that matter most.
- Black start and islanded operation
- Critical-load classification and control
- Coordinated diesel-generator operation

Green Hydrogen
Green Hydrogen Power Supply
Purpose-designed renewable power systems support electrolyzer operation with controlled, high-quality electricity and coordinated balance-of-system equipment for reliable green hydrogen production.
- Renewable power conditioning for electrolysis
- Stable DC/AC power and energy buffering
- Integrated power-system equipment and controls

EV Charging + Solar + Storage
Solar + Storage EV Charging
Integrated charging stations use onsite solar and batteries to reduce grid connection requirements, control charging peaks, and raise the share of clean energy delivered to electric vehicles.
- Reduced transformer and grid capacity demand
- Charging peak shaving and cost optimization
- Higher utilization of onsite green power
